Zerodha vs data

does real time data match that of zerodha real time data?

Can I use the historical charts on to trade on zerodha?
Because zerodha does not provide historical intraday data for MCX and data vendors are too costly.

@Karan23 data is real-time as well except that there might be streaming lag. uses data of active contracts in the historical charts. For eg: if you are viewing the crude data from Nov1 -19, the data in is of Crude19NovFut contract and from Nov 20 the data is of Crude19DecFut Contract. You might also need to factor the premium which new contracts would have on every expiry to test your models.
